Teaching

  • EG-120 Strength of Materials

    The aim of the module is to gain understanding into how engineering structures and components transmit loads and other external actions by means of internal stresses and how these stresses lead to strains and displacements. The course aims to explain the simple models of beam behaviour, concepts such as Mohr circle of stress and the relationships between stress and strain. Relevant case studies will be used to illustrate the importance of these subject areas.

  • EG-283 Mechanical Deformation in Structural Materials

    Following on from the first year module "Mechanical Properties" this module provides further detail about the deformation characteristics of a wide range of engineering materials. The course aims to develop the understanding of topics taught in the first year module by application to high performance materials such as titanium and nickel. Further understanding of deformation and damage mechanisms is gained through targeted units on elasticity, plasticity, alloy strengthening, mechanics of materials, fatigue and creep. The knowledge provided then allows for topics such as methods of mechanical testing and additive layer manufacturing. The module then seeks to draw these topics together by considering application to three main material classes, metals, ceramics and composites.
